Hoya Plant Care

Hoya blooms, like mop head hydrangeas, grow in a ball-shaped cluster. The plants have woody stems with waxy leaves that are evergreen. A hoya plant can be trained like a vine or let to drape over the side of a container.

Hoya plants will cling to a little trellis, adding vertical interest to tropical container garden. Any pond, fountain, or other water feature in landscape would benefit from the moist climate.

Hoya plants should be kept out of direct sunlight, since this might cause the leaves to burn. They require strong yet indirect lighting. In the spring and summer, water the plant often enough to keep the soil wet.

Soil and Fertilizer

Hoyas should be planted in a well-draining, lightweight soil mix. If there is too much moisture, the roots will rot. Provide a freely draining “soil” medium, such as a cactus and succulent mix or a mixture of one part regular potting mix and one part perlite.

Hoyas should be fertilized once a month, according to the International Hoya Association, with a fertilizer nitrogen, phosphorus, and potassium. During the growing season, the plant can be treated on a daily basis, preferably with a nitrogen-rich fertilizer.

Light and Water

Hoyas thrive best when they get bright, non-direct sunlight. Sunlight is essential for a Hoya plant, however indirect sunlight is better. If hang the plant directly in the window the leaves will burn from the direct heat of the sun.

During the growth season, provide water hoya flowers lightly and often. It requires less frequent and lower quantities of water during the winter. The Hoyas can probably be watered once a month because they are semi-dormant.

Temperature and Humidity

The Hoya flower falls into a form of hibernation throughout the winter months, so keep the plant in a colder setting with temps between 10 and 15°C. This flower plant should be shielded from high temperatures, like vents and draughty windows.

As a tropical plant, Hoyas thrive in warm and moist, humid climates. Hoya plants require high humidity and temperatures in general; species prefer colder and drier air. Hoya species with thicker leaves are tolerant of dry weather than varieties with more delicate leaves.

How To Grow Hoya Plants

Hoya plants are known to grow in woods, where they thrive in the hazy light. These plants are sensitive to direct and bright light, which can cause leaf burning. They do well in sunshine only if they are kept in the shade during the day.

They grow well in moderate to high humidity levels, thus they are suitable for growing in regular household situation. To keep Hoya plant healthy, keep it away from anything that might dry it out.

Because it might be harmed by dry air, use an electric humidifier or spray the plant with a water mist every couple of days to boost the humidity around Hoya.


Pruning is not a necessity, but if you want a bushier-looking plant, this will be an useful. Vines may be selectively pruned and then used to propagate new plants.

Use garden snips to prune this houseplant. Wipe them down with a paper towel soaked in hydrogen peroxide to sanities them. This will prevent from spreading any hidden diseases to prized plants.


Hoya plants can be propagated using stem cuttings or air layering. Include a few of healthy leaves! It is possible to propagate Hoyas from leafless cuttings, but it is more risky!

Seeds, leaf cuttings, stem cuttings, and layering can all be used to propagate oyas. However, these plants’ seeds are only viable for a few days, making seed propagation hard. When it comes to roots leaves, the majority of gardeners fail to generate a new plant in this manner.

Pests and Diseases

Sap-sucking pests like as aphids, mealy bugs, and spider mites attack Hoyas. All of these may be managed using neem oil. Wipe away insect remains with a clean, soft cloth once sprayed the plant.

Fungal infections are very common in hoya plant diseases. Botrytis blight, which appears as grey areas on plant, can cause rot and destroy it. Fungicide is used before repotting in sterile potting medium.
